Ultimate's Gradient-3^TM archwires are designed to generate three thermal (heat-activated) forces throughout the arch. Applying the appropriate force according to root strength allows for efficient movement and greater patient comfort.

• Gradient-3^TM Archwires offer 3 designed forces in one archwire.
• Superior shape integrity.
• Smooth, gradual increase of force loads from anterior to posterior regions.

The anterior region has the lowest heat-activated force, as the anterior teeth have the lightest roots. The force increases through the bicuspid region, having a slightly greater heat-activated force to move the larger rooted bicuspids. The posterior region has the greatest heat-activated force of the archwire, for moving the strong-rooted molars.
